5.8.1 Fan
As a rule the fan is fitted on the highspeed shaft of the gear unit and is protected from accidental contact
by an airguide cover. The fan sucks air through the grid of the airguide cover and blows it by way of its
air ducts on the side along the gearunit housing. It thereby dissipates a certain amount of heat from the
housing.

For a detailed illustration of the gear unit and the position of the addon parts, refer to the drawings in the
gearunit documentation.
NOTICE
Material damage
Risk of overheating of the gear unit through insufficient air feed.
For gear units fitted with a fan, sufficient space must be allowed for air intake when fitting the safety
guards for the coupling or other components.
The required distance is shown on the dimensioned drawing in the gearunit documentation.
It must be ensured that the airguide cover is correctly fastened. The airguide cover must be protected
against damage from outside. The fan must not come into contact with the airguide cover.
NOTICE
Material damage
Risk of overheating of the gear unit because a layer of dirt on the gear unit or a dirty air filter is having an
insulating effect.
The cooling effect is considerably reduced if the fan and the housing surface are dirty.
Observe instructions for cleaning in section 10, "Maintenance and repair".
